PPP connection has been opened automatically when AT+CFUN=1 is done and PDN has been activated even without PPP request using AT#XPPP=1. This is now changed so you need to issue AT#XPPP=1 in order to start PPP. This can be done before or after AT+CFUN=1.

Enabled CONFIG_MODEM_BACKEND_UART_ASYNC_HWFC forgotten in PR #6.

Before properly reviewing this:

Can we instead get rid of AT#XPPP (or just deprecated it) and instead emulate ATD*99#?

It would be a step towards standard. As an example: https://onomondo.com/blog/at-commands-guide-for-iot-devices/

Good to go in.

I think the ATD proposal can be followed up later.
